There's a "heavy" piece of news!
Super weighty ~
That's 30,000 tons!
recently
The largest freight heavy-haul train on the mainland at present
Shuohuang Railway of National Energy Group
30,000-ton heavy-haul train
Successful operation!
It marks the mainland's 30,000-ton heavy-haul train
Achieve new breakthroughs in the application of fully autonomous technology
Open a new chapter in the energy field of transportation power
Heavy-haul railways are the total major trains,
Railways with large volumes and long transport distances
Not really
Heavier and more wagons on the wagons
It's that simple
After the load is heavier
Run, run safely, stop
All need the blessing of technology
There's a saying
Passenger transport looks at high-speed rail, freight looks at "10,000 tons"
The train was loaded with 324 wagons of coal
The total length is 4,088 meters, and the total weight is about 32,400 tons
It is the Continental Railway at present
The longest and largest heavy-haul combination train
It is towed by 4 high-power AC electric locomotives of Guoneng
The total power is equivalent to more than 52,000 horsepower
The coal carrying capacity of the "10,000-ton train".
Generally, it can reach two to three times that of ordinary trains
Transport capacity and efficiency have been greatly improved
The "steel dragon" is running
It's technology that runs
It will also run out of efficiency and effectiveness
Development of "10,000-ton train"
It is to ensure the security of energy supply
The mainland's coal resource endowment
Decided the continent
The pattern of "western coal transportation to the east" and "northern coal transportation to the south".
Railway transportation has the characteristics of large capacity, long distance,
High efficiency, not constrained by climatic conditions, etc
It is the safest and main way to transport coal
Therefore, it is necessary to develop the railway transportation industry with high quality
This time, a 30,000-ton heavy-haul train was successfully operated
It adopts a number of self-developed products in mainland China
Advanced heavy-haul combined train control technology
The whole process is safe and efficient
If a 30,000-ton heavy-haul combination train is run every day
Compared to 20,000-ton trains
It can increase the railway traffic by 3.15 million tons a year
And not only in the field of rail transport
It is the ballast stone and stabilizer of the energy supply
A number of central enterprises in coal
Mining, transportation, washing, refining and other industrial chains
all have a "Big Mac" full of gold content
These heavyweights are constantly evolving in terms of technology and volume
It ensures that the pulse of the coal industry continues to beat
Coal Sea Dragon, Deep Tunneling!
Fewer people and more intelligent
It is the development aspect of coal mine excavation work
With the help of the "Coal Sea Dragon".
Workers operating coal tunneling remotely has become a reality
"Coal Sea Dragon"
It is independently developed by Taiyuan Research Institute of China Coal Science and Industry
With the anchor digging machine as the leader
"Trinity" rapid tunneling system for excavation, support and transportation
Increase the tunneling efficiency by more than 2 times
60% reduction in workers
He has set a world record for roadway excavation many times
▲China Coal Technology Taiyuan Research Institute intelligent anchor digging machine
thereinto
The retractable drum is responsible for cutting the coal
At the same time through the airborne anchor drilling device
Carry out the support of the roof and side panels
Keep people and equipment safe
The cut lump of coal consists of two rotating rake claws at the front end
Dial to the transport department in the middle
transported to the back continuous transport system
A steady stream of transport out of the shaft
▲The "dragon's teeth" at the front end of the "coal sea dragon" working face in the No. 2 mine of Huangling Mining
It is worth mentioning
At present, the latest version of the "Coal Sea Jiaolong" equipment
It also adopts an intelligent centralized control system
It is equipped with a full line of coverage from the work surface to the floor
Video surveillance and voice interaction system
This makes the "dragon", "ear" and "eye" clear
After the "Coal Sea Jiaolong" adopts this system
The whole process of excavation operation is automated
Improved safety and reliability of tunnelling
The operator only needs to follow the human-computer interface
In the underground centralized control center and surface dispatching platform
Remote operation
The whole process of complete equipment can be realized
Remote one-key start and stop
▲The "Coal Sea Jiaolong" centralized control center in the No. 2 mine of Huangling Mining
The world's largest!
August 2023
The world's largest power, ultra-large mining height intelligent high-end shearer
MG1250/3430-WD series shearer
It was launched in China Coal Science and Technology Shanghai Research Institute
Push the development of the world's mining machinery to a new height
This series of shearer sets
Intelligent perception, intelligent control, intelligent diagnosis and intelligent communication
All in one
Developed for 7 to 10 m thick and extra-thick coal seams
Cutting power 1250 kW
Traction power 250 kW
The installed power is 3430 kW
The maximum mining height is 10 meters
And its design effectively solves it
When using traditional crafts
The problem of low resource recovery rate of coal mining face
It can meet the needs of efficient coal mining
Only 2 units of this equipment are needed for coal mining
It can meet the annual coal demand for power generation in Shanghai
One shovel goes down, that's 60 tons!
In the coal excavator world of open-pit coal mines
There is a trump card product known as "the first digging in China".
XCMG's XE7000 hydraulic excavator
The XE7000 is 23.5 meters long and 9.09 meters wide
It is 9.44 meters high and weighs 700 tons
The maximum horizontal push distance on the ground is 4.69 meters
The maximum excavation radius is 16.7 meters
2020
After the first XE7000 mining excavator was successfully launched
With a bucket of 60 tons of coal loaded "Big Mac",
The power of nearly 30 family cars
A "move" to become the "master equipment" of the coal mining industry
XE7000 equipment is intelligent and highly automated
Sensitive operation and fast response
It greatly improves the efficiency of the operation
It is very ideal in large mines
High-end mining equipment
